1 Application fine This invention relates to a inachine par :ticularly designed for winding yarn on the spools used in weaving nioquette carpet It is d 'irable that a substantially uniform k h of yarn should be placed on each spoolyso that a min unn amount of yarn inavireinainon the soools after the desired cf no; i re b worenl i the object. of my invention to provide a simple and effective device by which the winder may be stopped tit-"the end of a predetermined pcriodof opera ion.

"A furtherobject is to so arrange and 1ppl the stop inotion that the winder remains at all times under on ol. of theoperatorand ll'lflffl)? c 1 i coped S desired *during the winding a spool without interfering withthe accurate operation of the stop motion the fdcterir' d point. To

this end, my invention-cont plates such a relation between the stop mot on and the 'nia'nual control mechanism-thetthe operation of the stop motion is effective to disable the control inechanisrn in all positions thereof. a I t My invention further relates to arrangements and combinations of parts which will be hereinafter described a rd more particw larlypointed outinthe appended claims.

Referring to the'drawings I have shown a winder of the general tvpe disclosed in my prior Patent No. 1,337,727, issued April 20,

1920 and comprising a frame 10 supporting a: measuring roll 11 having connections (not shown) to driving shaft- 12rotatabl'e in hearings in the lower part of the frame 1O.

A driving pulley 13 is loosely rotatable on the shaft 12 and may beforced outward againsta friction disc li to rotate the shaft 12.7 V

-The pulley 13 is provided with a hub *Jetocer 18, 1922.

[A hand'lever 35 is provided on the shwf for resetting the device aswill be hereinafter described.

mounted on the forked arms of alever 17 secured to a clutch shaft 18; A bell crank 19 is tired to t-heend of the shaft 18 andthe upwardly extending armof the bell crank pivotally supports a'control lever 20.

, An arm 21 of the lever 20 is connected by togglenieinbers 22 to the horizontally e1;- tending arm 23 of the bell oranlziO; A

spring 2 1 v normally maintains the toggle members 22 in theoperative relation'showrr in F 1g. 5, determined by, a stop 25.

An arm 26 is associated with the lower to gle member 22 and is'connected by a link or chain 27 to an arm 28 on a rock shaft 29. The shaft 29 is inounnted in bearings on the frame 10 and supports a second arm 30 hav- .ing a pin and slot connection with the lower g i 1 U1 11 end Or a stop lever 31. inc upper end of "the leverfll engages the face of a'disc 32 having a positive worm and-gear driving connection from the measuring roll 11. The pitch of the worm and thesizeof the gears may be selected" to cause the disc 32 to lo tate once for any desired number of revolutions of the measuring roll 11. 7

'lhediso32 is provided with a notch or recessSi-B at one pointin its circumference and a spring 34F. causes the upper end of the lerer 31; to enter the notch whenever the end ofthe lever is in alignment therewith.- t'29 The control lever 20 is commonly provided it maybe moved to the leftxto cause the SSfiCHUSETTSQA COR-IEQRATIQNLGF MASSACHU- having a groove 15 whichreceives blocks 16" witha l-znee pad no at'itsupper end by which pulley 13 to-engage the disc 14 and start th winder. Av heavy coilspring (Fig. 1)

acts to immediately disengage the drlving connections as soon as pressure on the pad 86 is released. A link 38 connects the lever 20 to a siinilar lever at the opposite side of the machine, as fully disolosedin my prior patentq thusperinitting the machine to be controlled from either side v Having thus described the construction of my improved winderythe operation thereof is as follows: i 1 i The gearing between theineasuring roll 11 and the disc 32is first selected so that the nieasuiing roll will pass the desired length of varn while the disc/'32 is completing a single revolution. Assuming-that the ma lever 31 disposed in the notch 33, anew spool is placed in the machine and the winder is started by pressure upon the pad 36 of the control lever 20. The machine continues in operation until the disc 32 completes its single revolution, during which time, however, it may be started and stopped by the operator as desired by applying and releasing pressure on the pad 36.

hen the revolution of the disc 32 is completcd. the end of the lever 31 enters the notch 33, the. chain or link 27 is pulled upward, and the lower toggle member 22 is rocked to break the toggle, as indicated by the arrow on in Fig. 6. The bell crank 19 is thus released, regardless of the position of the control lever 20, and the spring 37 promptly disconnects the driving pulley 13. in order to start the machine, it is necessary to first use the handle 35 to withdraw the lever 31 from the notch 33 and to relieve the tension on the chain 27, permitting the spring 24 to re tore the toggle members 22 to their original position. \Vhile the lever 31 thus held out of the notch 33, the machine may be started bv the usual pressure upon the pad 36 of the lever 20.

it is thus evident that I have so arranged my stopping mechanism that the machine remains at all times under the direct control of the operator, except at the point when the disc 32 completes its revolution, at which point the manual control mechanism is disabled and the machine is stopped regardless of the application of pressure on the lever 20.

Having thus described my invention, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims but what I claim is 1. A, winder having, in combination, a measuring roll, driving mechanism therefor, means to make and manually maintain a driving connection to said driving mechanism, and a stopping device effective to disable said manual means and stop said measuring roll while said manual means remains in its normally operative position.

2. A winder having, in combination a measuring roll, driving mechanism therefor, a manual shifting lever for said driving mechanism, a connection through which said lever is effective to render said driving mechanism operative to drive said measuring roll, and automatic means effective to disable said connection and stop said roll after a predetermined actuation thereof and while said shifting lever remains in its normally operative position.

3.1; winder having, in combination, a measuring roll, driving mechanism therefor, including a clutch operating shaft, :1 manually operated controlling lever for said shaft, means to connect said lever rigidly with said shaft, and automatic devices effective to disable said connecting means and release said shaft from said manually operated controlling lever.

4. A winder having, in combination. a measuring roll, driving mechanism therefor, a manually operated controlling device for said mechanism freely movable to operative position, and additional and automatic means effective to disable said manually operated controlling device and thereby cause disengagement of said driving mechanism while said controlling device remains freely movable and in its normally operative position.

5. In a winder, a measuring device, driving mechanism, and control means for said driving mechanism, said control means including a clutch, a clutch operating shaft, abell crank fixed thereon. a control lever pivoted to one arm of said bell crank, a toggle connection between said lever and the other arm of said bell crank, and means to break said toggle connection, said latter means being normally held out of operation by said measuring device during a predetermined operation of said measuring device.

In testimony whereof I have hereunto aiiixed my signature.
